Three representative authors specializing in each subject

This textbook is updated annually to reflect the latest trends by three veteran professors who have been teaching hygienist classes for over 20 years.
The lectures and textbooks of Professors Lee Seung-hoon (Environmental Hygiene, Hygienic Entomology), Kim Ji-yeon (Food Hygiene), and Kim Hee-young (Hygiene Law, Public Health) are proven by the numerous success stories of passing the hygienist exam.

Reflecting the latest exam trends for passing the 47th Hygienist Exam

The past questions for the Sanitary Technician Exam were first made public starting with the 42nd exam, but from April 2025, only the most recent past questions from the first exam will be made public.
We have thoroughly reflected the contents that must be checked and the contents that are highly likely to appear on the actual exam in accordance with the actual exam question trends.
This is the 5th edition textbook, which was first introduced in preparation for the 43rd edition, and has been further supplemented to match the latest trends through the 2nd to 4th editions.

A study guide that allows you to communicate with the authors at any time

You can communicate with the authors at any time through the community of 'Nutritious, Hygiene-Filled (https://cafe.naver.com/clubdietitian),' the number one cafe for domestic hygiene exams.
We can confidently say that Open Hygiene Exam Preparation is the only one that quickly shares the latest information and materials related to the exam and allows for quick communication with actual authors.

A 37-year tradition of consistently providing on-site lectures to help you pass the hygienist exam every year!

This is a study guide for the hygienist exam adopted by Daebang Open Academy (https://www.daebangmajor.com).
'Daebangyeollim' is filming and updating its latest video lectures for the hygiene technician exam every year, filming them exactly as they were recorded at the academy.
Be careful, as there are companies that reuse existing lectures or change only some of the lectures to deceive you.
